ameno OVEN ELECTRIC BURNER.

pplication led September To all .whom it may concern.'

Be it knownfthat ROBERT H. MAcINNns, a subject of the King of Great Britain, residing at Hamilton, in the county of lVentworth and Province of Ontario, Canada,

has invented certain new and useful Iniprovenients ini a Hinged Oven Electric Burner (Case 2), of which the following is al specification.

l@ This invention relates to electric stoves and has special reference to oven heater elements, sometimes called an oven burner, for such stoves.

@ne important object of the invention is to generally simplify and improve the construction of devices of this character so 'that the element constitutes a unitary structure of novel arrangement speciallyadapted for use as a hinged burner. Hinged burners have been in use heretofore for the purpose of permitting the burner to be elevated to a standing or perpendicular position so that the bottoni of the-oven beneath their nornaal positionmay be cleaned out, but these burners have been too cumbersomeand 'coinplicated to be ellicient.

A second inportant object of the invention is to provide an `improved form of c such heater element wherein the swivel 3o parts are so constructed and arranged that they may be readily assembled in manufacture or disassembled for repairs and replacement. Y

lilith the above and other objects in view as will hereinafter be apparent, the invention consists of certain novel details of construction and combination of'parts as will he hereinafter fully describe@ illustrated intheaccoinpanying drawing, and pointed 4G out in the' claims hereunto appended.

Referring to the drawing Figure l is a plan view of an oven heater element ror burner constructed in accordance with this invention; and

Figure 2 is a. sectional front elevation taken on the line 2--2 in Figure l..

Similar reference characters refer to similar parts throughout `both views. f The. preferred use of the improved ov`en burner is with the t'ype of oven having a recess, or well, as it is sometimes called, in the bottom thereof, in which the burner is con- 12, 1924. Serial No. 737,317.

fined. This type of oven is shown on the drawing, the bottom thereof being indicated by the numeral l0, and the recess or well hy the nuineral 1l. Theheating resistance holder part of the burner is preferably of the rectangular type comprising a lower reflector or heater plate 12, and an upper re- Hector plate 13, the upper plate being removably slidable in parallel overturned edges lll of the lower plate. 'lhe'upper plate is provided with a plurality of parallel slots through which project upwardly the webs l5 of a plurality of refractory' resistance supports having base flanges lo held between the two plates. Through openings in the webs l5 is woven the resistance wiring 17. This rectangular struc-` ture is recessed in a hinged frame which "normally rests upon the bottoni of the well ll. The frame is comprised of lateral rails 18 and a plurality of cross connecting meinbers 19 integral therewith. A perpendicular flange or rib` 20 extends around the frame, and this Harige forrns the recess for the'heating resistance holder. The heating `resistance holder is bolted to the frame, the

bolts 2l passing through the frame and said y upper and lower plates, so 'that the entire structure may be disassembled by the -reinoval of said bolts.

The frame is hinged to the bottoni/of the oven recess ll` at a point designated. by i8 bv means of the projecting ends of the4 lateral rails 18 .which form or, constitute hinge leaves, and the end cross ineinher on the opposite end of vthe structure is provided with a projecting hasp 22to receive an eye 2,3 for pinning the burner in normal posim tion.

There has thus been produced a simple 'and efficient device of `the class described and for the purpose specified.

,Having now fully disclosed the invent-ion, what l specifically claim. iszl, ln an electric oven burner, lateral rails or straps, a plurality of cross rneinhers connecting the rails, flanges on said rails and on` the end cro/ss niembersfsaid flanges forming a recess in the structure constituted by theails and cross members, and a heaterl element resting in said `recess.
